Compositae, G. V. Pope. Flora Zambesiaca 6:1. 1992

Morphology General Habit
Annual perennial or biennial herbs (spiny subshrubs), glabrous, with or without stems, sometimes caespitose, occasionally stoloniferous.
Morphology Stem
Stems or flowering stalks 1-several, branching above or simple.
Morphology Leaves
Leaves cauline and alternate, or radical and rosulate, entire or sinuate-dentate to runcinate-pinnatipartite, often acicular-denticulate on the margins.
Morphology Reproductive morphology Inflorescences Capitulum
Capitula few to numerous, subsessile or shortly stalked, often in lax irregular corymbs, sometimes solitary, or in clusters along the branches.
Morphology Reproductive morphology Flowers Receptacle
Receptacle epaleate.
Morphology Reproductive morphology Inflorescences Bracts Involucre
Involucres narrowly cylindric-campanulate.
Morphology Reproductive morphology Inflorescences Bracts Phyllaries
Phyllaries 2-several-seriate, becoming ± swollen and corky towards the base; the innermost subequal, usually greatly exceeding the outer.
Morphology Reproductive morphology Flowers Florets
Florets few to many, yellow, or the ligule sometimes purplish or red outside; anthers sagittate at the base with the auricles shortly setaceous-acuminate; style branches long slender, sweeping hairs long.
Morphology Reproductive morphology Fruits
Achenes pale-brown to black, subterete or somewhat angular, or compressed, sometimes apically attenuate or beaked, ribbed; ribs 5-many, uniformly narrow or somewhat inflated, smooth or muricate, glabrous.
Morphology Reproductive morphology Seeds
Pappus many-seriate, of setae only or of setae intermixed with numerous down-like hairs.

Morphology General Habit
Annual to perennial herbs, subshrubs or shrublets, sometimes spinescent, with white latex, chiefly glabrous
Morphology Reproductive morphology Inflorescences
Flowering stems terminating in synflorescences with few to many capitula Capitula c. 8–45-flowered; involucre slender, phyllaries mostly with distinct scarious margin, in a few outer series and an inner series of distinctly longer, equal, linear-lanceolate ones; receptacle naked
Morphology Reproductive morphology Flowers Florets
Florets all ligulate, 5-toothed, bisexual, of some shade of yellow; anthers with sagittate basal and rounded apical appendages
Morphology Reproductive morphology Fruits
Achenes homomorphic or heteromorphic, usually slender, c. 2–6 mm long, cylindric to subfusiform, the marginal somewhat curved and flattened; pappus persistent or deciduous, either of ± numerous uniform bristles or of ± numerous outer downy hairs and fewer inner bristles; bristles and hairs scabrid.
Distribution
Genus of 55 species mainly in Africa and south-western to southern and central Asia, six in Mediterranean Europe, one each in western Australia and, introduced, in the New World (Caribbean and adjacent regions).
